ABSTRACT
PURPOSE:
This study aimed to examine the success rate of repeat endoscopic third ventriculostomy (redo-ETV) according to pattern of ventriculostoma closure based on observations in 97 paediatric redo-ETV patients.METHODS:
Clinical data and intraoperative video recordings of 97 paediatric hydrocephalus patients who underwent redo-ETV due to ventriculostoma closure at two institutions were retrospectively analysed. We excluded patients with a history of intraventricular haemorrhage, cerebrospinal fluid (CSF) infection or CSF shunt surgery and those with incompletely penetrated membranes during the initial ETV.RESULTS:
Verification of ventriculostoma closure was confirmed with cine phase-contrast magnetic resonance imaging and classified into 3 types type 1, total closure of the ventriculostoma by gliosis or scar tissue that results in a non-translucent/opaque third ventricle floor; type 2, narrowing/closure of the ventriculostoma by newly formed translucent/semi-transparent membranes; and type 3, presence of a patent ventriculostoma orifice with CSF flow blockage by newly formed reactive membranes or arachnoidal webs in the basal cisterns. The overall success rate of redo-ETV was 37.1%. The success rates of redo-ETV according to closure type were 25% for type 1, 43.6% for type 2 and 38.2% for type 3. The frequency of type 1 ventriculostoma closure was significantly higher in patients with myelomeningocele-related hydrocephalus.CONCLUSION:
For patients with ventriculostoma closure after ETV, reopening of the stoma can be performed. Our findings regarding the frequencies of ventriculostoma closure types and the success rate of redo-ETV in paediatric patients according to ventriculostoma closure type are preliminary and should be verified by future studies.Palabras clave
